question about sound normalize

[cowby]

Hi,

 

I have Sound forge 9 and Audtion 3.0 ... But if you think that other wav editor can do the following, pls let me know.

 

all I want is to use a Audio editor to normalize the whole wav form or batch processing for 10 wav files at a time. Right now, I use the above editors by using trial and error approach to normalize the wav files. Say normalize by 110% or 115% and so on. But sometimes after the normalization, the peak level exceeded >> 0db. Is there a way to overcome it by not using trial and error approach ?

 

Thanks!
